Hello,I just finished high-school (sixth form in the UK) and I will start studying Mathematics and Economics course at university soon. I enjoyed physics a lot in high school (almost chose to study it at uni) and therefore don't want to stop learning about it. How can I self study physics...

Thanks.

Hello, I just finished A-Levels (high school) and I bought two maths books to study over summer. I got Spivak's Calculus and "A Course of Pure Mathematics" by G.H.Hardy. With which book should I start? Or should I learn from them simultaneously? Regards, NeoXx

But as far as I know all DVD types have the same track spacing? As well, I measured the track spacing similar to a normal DVD, and still got 2.8GB...

This is my second experiment where I got similar data as one mentioned in my first post.

Hello, I finished an experiment of finding out the track spacing of a CD and a DVD. My laser wavelength was 654nm which I used to calculate track spacing of the optical discs. I got a track spacing of a CD 1.57um which is close to a real value of 1.6um, and the track spacing of a DVD...

Thank you for your answer. Yes I am familiar with some calculus. Will take a look at those books. :)

Hello, I am an A-level student in Cambridge finishing the A2. From doing Mathematics I got very interested in Calculus, and now I'm looking for a complete course for Calculus in order to learn it at a much higher depth. Can anyone suggest a great book on Calculus? :smile: Regards...

Hello, I have to do an experiment in which I will investigate the diffraction grating of a CD and a DVD. I want to find out the spacing of tracks on both of them and thus find how much information can be stored. Also I want to compare them (density of tracks etc.) and maybe even suggest...

I would love to investigate the behaviour of light such as in double slit experiment or glass reflection and prove the photoelectric effect or wave particle duality. However the lab does not have the required equipment for those experiments. There is the equipment to fairly demonstrate the...

Yes it was my first goal. But my goal in this experiment is not to demonstrate Wave-Particle Duality anymore but to investigate diffraction and interference of light in optical discs. My goal here will be to show the differences between those optical discs and maybe conclude how they could...

What do you mean?

After speaking to my physics teacher I decided that I could investigate the diffraction and interference happening on CD/DVD and Blu-ray discs. Investigating photoelectric effect by doing a nicer experiment would require equipment our school lab doesn't have (potassium metal etc.). What do you...

Giving it another thought I was wrong in saying that the experiment will be short especially since I will have to read a lot about the topic and write the report as well. I concluded I will investigate the photo electric effect and do the experiment. Thanks for the help everyone! :)

Photoelectric effect experiment seems interesting. However it seems to me that it is a very short experiment, correct me if I am wrong.
